Maybe this is a very naive solution, but couldn't we solve the problem
of getting audio data from PD into non-jack apps (that support some kind
of plugin), by writing a very simple (LADSPA, VST, AU etc.) plugin that
acts as a jack client. 


Audacity -> LADSPA jack client plugin -> jack -> PD -> jack -> LADSPA
jack client plugin -> Audacity

The simplest case would use one 'jack client plugin' instance for each
audio channel to/from PD.

I've been meaning to implement this for a while, and maybe there's a
glaring flaw, but I can't see it right now..
